Construction Update: Caisson work at Hubbard and Wells

221 Hubbard 421 Wells

A CTA Purple Line trains passes construction at Hubbard and Wells.

Case Foundation is on the case at Hubbard and Wells, where Centrum Partners is developing not one, but two new buildings for River North: a 9-story office building at 412 North Wells Street, and a 23-story, 193-unit apartment tower at 221 West Hubbard Street. You can get a great view off progress by hopping a Purple or Brown Line train at Merchandise Mart and riding north.

**Better yet, get on a train at Chicago Avenue, get in the last car, ride south, and take a lap through The Loop. Back-of-the-train views are the best.)**

The two Hirsch Associates projects got foundation permits a week apart at the end of June and early July, the parking lot it used to be was immediately fenced off, and Case brought their big toys in to start drilling caissons. Once that’s all done, Linn-Mathes takes full control of the process, getting these two glass edifices off the ground and heading skyward.

Site Prep Underway at Centrum Hubbard

First the cars were kicked out of the parking lot. Then the fencing went up. Then the Divvy station got kicked to a different curb. And now, there’s scraping and digging going on at 221 West Hubbard (and 412 North Wells, for that matter) in preparation for Centrum Partners’ two-building development in River North.

Designed by Hirsch Associates Architects, 412 North Wells will be a 9-story office building, next to 221 West Hubbard’s 23-story apartment tower.

Linn-Mathes, general contractor for both structures, must be champing at the bit to get going on this lot. It was hoped building permits would be filed around the first of April, but some soil samples turned up negative results, and that set things back awhile. But they’re up and running now. Jump on a Brown or Purple Line train and enjoy the fun.

Last week, the residential tower from Centrum Partners at 221 West Hubbard Street in River North got a permit from the City of Chicago to begin foundation work. And now, officially, that lot at Hubbard and Wells is twice as busy.

Yesterday, a permit was filed for caisson work to get started for the other half of this couple, the 9-story office building at 412 North Wells Street. The two towers, both designs from Howard Hirsch of Hirsch Associates Architecture, were delayed slightly by negative results from soil sampling on the site. But the delay is no more. With permits in hand, general contractor Linn-Mathes can flood that lot with caisson equipment, and get to drilling.
